However, due to increased sea surface temperatures, sea ice in areas such as the Arctic is melting. Of those gases, known as greenhouse gases, water vapor has the largest effect. This is important in terms of climate change because ice has a high albedo, and so reflects most solar radiation back into the atmosphere, meaning the ice remains cold. It is a Latinicized term meaning "whiteness". Albedo is measured as the fraction of incident light that the surface reflects back in all directions. noun [physics, meteorology, astronomy] The fraction of incident light or radiation reflected by a surface or body, commonly expressed as percentage.
